§ 59.108. Water supply.

 The water supply shall meet the following requirements:

   (1)  Water for milkhouse and milking operation shall be from a supply properly located, protected, and operated and shall be easily accessible, adequate, and of a safe and sanitary quality.

   (2)  The water supply shall contain a Most Probable Number of Coliform Organisms (MPN) of less than 2.2/100 ml by the multiple tube fermentation method or less than 1/100 ml by the membrane filter technique.

   (3)  No cross-connection shall exist between a safe water supply and any unsafe or questionable water supply or any other source of pollution.

   (4)  There shall be no submerged inlets through which a safe water supply may be contaminated.

   (5)  The well or other source of water shall be located and constructed in such a manner that neither underground nor surface contamination from any sewerage system, privy, or other source of pollution can reach such water supply.

   (6)  New individual water supplies and water supply systems which have been repaired or which otherwise become contaminated shall be thoroughly disinfected before being placed in use. The supply shall be made free of the disinfectant by pumping to waste before any sample for bacteriological testing shall be collected.

   (7)  All containers and tanks used in the transportation of water shall be sealed and protected from possible contamination. These containers and tanks shall be subjected to a thorough cleaning and a bacteriological treatment prior to filling with potable water to be used at the dairy farm. To minimize the possibility of contamination of the water during its transfer from the potable tanks to the elevated or groundwater storage at the dairy farm, a suitable pump, hose, and fittings shall be provided. When the pump hose and fittings are not being used, the outlets shall be capped and stored in a suitable dustproof/enclosure so as to prevent their contamination. The storage tank at the dairy farm shall be constructed of impervious material provided with a dustproof and rainproof cover and provided with an approved type vent and roof hatch. All new reservoirs or reservoirs which have been cleaned shall be disinfected prior to placing them into service.

   (8)  Samples for bacteriological examination shall be taken upon the initial approval of the physical structure, when any repair or alteration of the water supply system has been made, and at least every 3 years; provided that water supplies with buried well casing seals installed prior to August 7, 1982, shall be tested at intervals no greater than 6 months apart. Whenever such samples indicate either the presence of bacteria of the coliform group or whenever the well casing, pump, or seal need replacing or repair, the well casing and seal shall be brought above the ground surface and shall comply with all other applicable construction criteria of this section; provided that when water is hauled to the dairy farm, such water shall be sampled for bacteriological examination at the point of use and submitted to a laboratory each month. Bacteriological examinations shall be conducted in a laboratory acceptable to the Secretary.

   (9)  Current records of water tests shall be retained on file by the permit holder.
